i ran a supermicro dual xeon 2.6 with a 350 powerman non-p4 rated power supply.
it had the regular 4pin 12v and a seperate 8pin 12v power. I just got adapter for those. At the time, I ran it with 4 IDE + 2 SCSI HDD, 3 CD/DVD ROM Drives
I recently upgraded to teh vantec 470a stealth because it had 10 4pin molex for drives. I had to use a lot of Y adapter before and it made my case a mess.
I dont think the asus had any special connectors.
